Purpose: The aim on this study was to establish the validity, reliability and efficiency of a Pain Self-Report Scale for elderly with dementia and compare these results with an observational pain rating scale. Methods: Study subjects were 136 elderly with dementia who were residents in a nursing home, geriatric hospital, or day care center. The subject's pain was measured by five self-report scales and observational scale. DS-DAT (discomfort scale-dementia of the Alzheimer's type) was used for pain behavior observational measure. Cognitive state was assessed using the MMSE (Mini-Mental State Examination). Results: Observational rating correlated moderately with self-report (r=.225~.585, p<.05) and tended to underestimate pain intensity. Test-retest reliability was high for all five self-report scales, and the correlation between these scales was very strong (r=.735~.856, p<.05). Comprehension rate of VDS (verbal descriptor scale) was 88.3%, and NRS (numeric rating scale) 69.9%, FPS (face pain scale) 66.9%, HVAS (horizontal visual analog scale) and VVAS (vertical visual analog scale) 65.4%. Conclusion: Nurses should not apply observational scales routinely in demented patients as many of these are capable of reporting their own pain. Self-report, the highest standard of pain measurement can be reliably performed in a large proportion of demented elderly.

This study purposed to standardize the Korean versions of the General Health Questionnaire, especially KGHQ-20 and KGHQ-30, through the evaluation of their reliability and validity. The two KGHQs, along with several other scales that measure psychological symptoms, were administered to 916 students and 102 chronically mentally ill patients at mental health hospitals in Korea. Both of the KGHQs were found to have high reliability based on test-retest correlation coefficients, internal consistency (Chronbach's ${\alpha}$) as scales, and item-total correlations for most of the items. The two KGHQ scores were shown to have high validity based on three methods of analysis; first, both KGHQ scores had highly significant correlations with most of other measures for psychopathology, such as SCL-90, CES-D, SDS, BAI, STAI; second, there were significant differences of the two KGHQ scores between the group of mentally healthy students and the group of chronically mentally ill patients; the validity of the KGHQ-30 was also derived from high sensitivity and specificity, which helped identify the best cut-off points: 15/16 for the KGHQ-30. The cut-off point for the KGHQ-20 was determined at 12/13 based on the mean scores and standard deviations of other scales as well as of the KGHQ-20.

The purpose of this study was to develope a questionaire measuring clothing behavior of elementary school children. At first, after pretest, the clothing behavior questionaire consisted of 70 items which were devidad. into 7 subscales i.e. Clothing interest. Clothing satisfaction. Clothing management, Clothing sex-role. Clothing comfort. Clothing conformity. and Clothing independence. Each item was rated on a 3-point scale. Samples were 447 boys and girls (4 th, 5 th, 6 th grade) of three elementary schools in Seoul. Korea. The data were analyzed by item analysis and factor analysis. Factor analysis was useful in attempting to establish contruct validity. Item validity was examined based on the correlation coefficients and item discriminating power through the chi-square. Reliability was examined based on the Cronbach's Alpha Reliability Coefficient and test-retest method. With this analysis the subscales were reconstructed to following 6 factors. Clothing conformity items were not clustered by the factor analysis. 52 items of 6 factors selected by the analysis. The factors characteristics were as follows: 1. Clothing interest (10 items) 2. Clothing satisfaction (11 items) 3. Clothing management (8 items) 4. Clothing sex-role (12 items) 5. Clothing comfort (6 items) 6. Clothing independence (5 items)

As online shopping is expanding rapidly, the damages undergone by consumers are also dramatically increasing. This research mainly focused on the damages experienced through Internet shopping. The purpose of this study was to develop a standardized scale to measure damages sustained through an Internet shopping mall. A preliminary 35-item scale was developed through a literature review, and 1,230 consumers responded to an online survey using the preliminary scale. This research was supported by the surveys conducted on consumers who had previously shopped at an Internet fashion mall. This research was conducted with the intention of not only supplying academic data on the damage sustained by consumers, but also understanding the consumers' basic behavior patterns. Then a series of tests, such as test-retest, item-to-total correlation, Cron bach's reliability coefficient and factor analysis, were conducted using the survey data and a final scale with 26-items was constructed in the end. The damage sustained in Internet shopping malls scale for consumers consisted of three factors: 1. Trouble with safety 2. Trouble with payment and delivery; and 3. Trouble with after-sales services.

The purpose of this study was to establish reliability and validity of the Northwick Park Neck Pain Questionnaire (NPQ) translated into Korean for neck pain patients. Sixty-two subjects (35 males, 27 females) with neck pain enrolled in the study. They completed a standardized self-administered questionnaire that included pain intensity, sleeping, sensory at night, duration of symptoms, carrying, reading and watching television, working, social activities, and driving. Reliability was determined by intraclass correlation coefficient (ICC) and Cronbach's alpha by internal consistency. Validity was examined by correlating the NPQ scores to the Visual Analog Scale (VAS) score. Test-retest reliability of the translated versions of the NPQ was good ICC(2,1)=.83 (95%CI=.85~.95). Cronbach's alpha value for NPQ was found to be .87 and this was statistically significant (p<.05). The criterion-related validity coefficients was .75 (p<.01). We concluded that the Korean version NPQ was shown to be a reliable and valid instrument for the assessment of neck pain.

Objectives: We developed a Korean translation of this questionnaire by sequential forward-and-backward translation. The purpose of this study is to validate the Korean version of the POEM, the "POEM-K" by Korean patients with atopic dermatitis (AD). Methods: A single-center prospective study was conducted with 50 participants diagnosed with AD. The POEM was translated to Korean version by an expert panel. Scoring Atopic Dermatitis (SCORAD) and Short Form 36 Health Survey (SF-36) were used as external comparators. Results: Twenty men and thirty women between the ages of 18 and 63 participated in the study. The test-retest reliability of the total POEM-K was estimated using the intra-class correlation coefficient (ICC) that showed a strong agreement (ICC = 0.72). By using Pearson correlation coefficients, we compared the POEM-K to SCORAD and yielded a concurrent validity that showed a significant result. The responsiveness of the POEM-K was represented by the effect size (ES) of 1.41 and statistically significant (p = 0.004). Conclusions: The Korean version of the POEM is a reliable, valid, and responsive disease-specific questionnaire for assessing the symptoms and quality of life of Korean patients with AD.

It is important to examine patients' subjective evaluation as well as objective measures and clinician's rating to assess voice disorders. This study aimed to evaluate validity and reliability of Korean-version of Voice Handicap Index (KVHI) and Voice-Related Quality of Life (KVQOL) with 113 adults with voice disorders and 111 normal adults. Content validity was verified by three experienced speech-language pathologists. Concurrent validity was revealed by examining the correlation among KVHI, KVQOL, and Voice Rating Scale as well as item discrimination coefficients. Total scores of KVHI and KVQOL of adults with voice disorders were significantly different from those of normal adults. Test-retest reliability and internal consistencies were significantly high in both KVHI and KVQOL. Correlations among scores of each subscale and total score were also significantly high in each tool. The study revealed that KVHI and KVQOL are suitable tools to be used in clinics and research areas in Korea, which can subjectively evaluate the effects of voice disorders on daily life as well as on quality of life.

This study is intended to create a tool which can identify the concept of consumption life level and to develop a standardized scale to measure consumption life level. Based on it, the concept and perspective of consumption life level was formed and then the scale for measuring it was developed. To develop the scale, the scale was firstly formed by extracting questions through a literature survey, and verifying validity through experts' opinions. Then the final scale was developed by conducting a questionnaire survey for consumers. A preliminary 27-item scale was developed through a literature review. 1000 consumers responded to an online survey using the preliminary scale. This research was made with the intention of not only supplying academic data on the consumer's consumption life level but also understanding the consumer's basic behavior patterns. Then a series of tests: test-retest, item-to-total correlation, and Cronbach's reliability coefficient and factor analysis were conducted using the survey data and the final 20-item scale was constructed in the end. The consumer's consumption life level scale consisted of 4 factors.

The purpose of this study was to determine reliability and validity of the Neck Disability Index (NDI) now in use for the first time in neck pain patients of Korea. Fifty subjects (26 males and24 female) with neck pain enrolled in the study. They completed a standardized self-administered questionnaire that include pain intensity, personal care, lifting, reading, headaches, concentration, work, driving, sleeping and recreation. Reliability was determined by intra-class correlation coefficient (ICC) and Cronbach's alpha by internal consistency. Validity was examined by correlating the NDI scores to the Visual Analog Scale (VAS) score. The Test-retest reliability of the translated versions of the NDI was good ICC (2,1) = .90 (95%CI .85 .95). Cronbach's alpha value for NDI was found to be .95 and this was statistically significant (p<.05). The criterion-related validity coefficients was .72 (p<.01). We conclude that the Korean version of NDI has shown to be a reliable and valid instrument for the assessment of neck pain.
